Answer:
- 60-month financing period: Monthly payment = $608.29 = 608 dollars 29 cents
- 72-month financing period: Monthly payment = $526.00 = 526 dollars
Step-by-step explanation:
As she has already made the down payment of 25% (= $10,000), the principal amount of the loan is now $30,000.
The monthly payment is calculated such that at the end of the financing period (60/72 months), the principal amount must equal to 0. As such calculations are complicated and prone to errors if done manually, please see the attached Excel working file for the detailed calculations.
1. 40% - 25%
ANSWER = 15%
2. There are 24 guests. 1/3 is 8 guests (drinks). 1/4 is 6 guests (desserts). The remaining guests (chips) = 24 - (8+6)
= 24 - 14.
ANSWER: 10 guests brought chips.
3. Not 100% sure about this one, though.
The area is 1112 ft x 912 ft = 1014144 sq ft. You divide the area of the kitchen by the area of the tile (144 sq ft), which is 7042.666667. Because its not a whole number, one of the tiles won't fit completely, so you get rid of it completely and round the number down.
ANSWER = 7042 tiles ???
4. Use BIDMAS for this one (Brackets, Indices, Divison, Multiplication, Addition, Subtraction)
-2[4^2 + (12)2]
Get rid of the (12) first
-2(4^2+24)
Now the other brackets.
4^2 (or 4 squaresquared, with the little 2) is 16, so you do 16+24.
-2(40) or -2 x 40
ANSWER = -80
6^8
You multiply 2 and 4 so 2x4=8
This is one of the exponent rules
Answer:
Blue = 12/58 * 100% = 20.68 = 21%
Red = 6/58 * 100 = 10.34 = 10%
Yellow = 21/58 * 100 = 36.20 = 36%
Black = 8/58 * 100 = 13.79 = 14%
Green = 11/58 * 100 = 18.96 = 19%
Step-by-step explanation:
Given the table :
Marble_color ____ Number of marbles
Blue ___________ 12
Red ___________ 6
Yellow _________ 21
Black __________ 8
Green _________ 11
Theoretical probability % = (number of favorable outcome / number of total possible outcomes)
Total possible outcomes = (12+6+21+8+11) = 58
Blue = 12/58 * 100% = 20.68 = 21%
Red = 6/58 * 100 = 10.34 = 10%
Yellow = 21/58 * 100 = 36.20 = 36%
Black = 8/58 * 100 = 13.79 = 14%
Green = 11/58 * 100 = 18.96 = 19%
Answer:
the surface area is 3140 square feet
Step-by-step explanation:
The computation of the surface area is given below:
Given that
Diameter = 20 feet
radius = 20 ÷ 2 = 10 feet
Surface area =
= 2 × 3.14 × (10)^2 + 2 × 3.14 × 10 × 40
= 6.28 × 100 + 6.28 × 400
= 628 + 25.12 × 100
= 628+ 2512
= 3140 square feet
hence, the surface area is 3140 square feet
